6 ``<PackageName>`` is the name given to the ``find_package`` call
7 and ``_ROOT`` is literal. For example, ``find_package(Foo)`` will search
8 prefixes specified in the ``Foo_ROOT`` CMake variable (if set).

11 This variable may hold a single prefix or a
12 :ref:`;-list <CMake Language Lists>` of multiple prefixes.
